Since commit 0a44dfc07074 ("wifi: mac80211: simplify non-chanctx
drivers") ieee80211_hw_config() is no longer called with changed = ~0.
rtlwifi relied on ~0 in order to ignore the default retry limits of
4/7, preferring 48/48 in station mode and 7/7 in AP/IBSS.
RTL8192DU has a lot of packet loss with the default limits from
mac80211. Fix it by ignoring IEEE80211_CONF_CHANGE_RETRY_LIMITS
completely, because it's the simplest solution.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
since there's no requirement to describe them in E820 and some
platforms require ECAM to work (Bjorn Helgaas)
- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
Le Moal)
- Remove last user and pci_enable_device_io() (Heiner Kallweit)
- Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)
- Skip waiting for devices that have been disconnected while
suspended (Ilpo Järvinen)
- Clear Secondary Status errors after enumeration since Master Aborts
and Unsupported Request errors are an expected part of enumeration
(Vidya Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout
correctable errors caused by a hardware defect; the errors cause
interrupts that prevent system suspend (Kai-Heng Feng)
- Fix EDR-related _DSM support, which previously evaluated revision 5
but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)
ASPM:
- Simplify link state definitions and mask calculation (Ilpo
Järvinen)
Power management:
- Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
apparently doesn't know how to put them back in D0 (Mario
Limonciello)
CXL:
- Support resetting CXL devices; special handling required because
CXL Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the
device supports, in addition to doing so if the size is >2GB
(Niklas Cassel)
- Simplify endpoint BAR allocation and setting interfaces (Niklas
Cassel)
Cadence PCIe controller driver:
- Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
Kozlowski)
Cadence PCIe endpoint driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the
BAR value (Niklas Cassel)
Freescale Layerscape PCIe controller driver:
- Convert DT binding to YAML (Frank Li)
MediaTek MT7621 PCIe controller driver:
- Add DT binding missing 'reg' property for child Root Ports
(Krzysztof Kozlowski)
- Fix theoretical string truncation in PHY name (Sergio Paracuellos)
NVIDIA Tegra194 PCIe controller driver:
- Return success for endpoint probe instead of falling through to the
failure path (Vidya Sagar)
Renesas R-Car PCIe controller driver:
- Add DT binding missing IOMMU properties (Geert Uytterhoeven)
- Add DT binding R-Car V4H compatible for host and endpoint mode
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the
BAR value (Niklas Cassel)
- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it
was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)
- Add DT binding J722S SoC support (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Add DT binding missing num-viewport, phys and phy-name properties
(Jan Kiszka)
Miscellaneous:
- Constify and annotate with __ro_after_init (Heiner Kallweit)
- Convert DT bindings to YAML (Krzysztof Kozlowski)
- Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming
Zhou)"

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

happen. We get IGTK IPN from mac80211 and set to firmware, and get latest
IGTK IPN from AOAC report then update to mac80211 after resume. When rekey
happen, also update new IGTK key info to mac80211. Furthermore, We

After enabling packet offload, the TX will be stuck after resume from
WoWLAN mode. And the 8852c gets error messages like
rtw89_8852ce 0000:04:00.0: No busy txwd pages available
rtw89_8852ce 0000:04:00.0: queue 0 txwd 100 is not idle

rtw89_8852ce 0000:04:00.0: queue 0 txwd 103 is not idle
If suspend/resume many times that firmware will download failed and
disconnection.
To fix these issues, We removed the rtw89_hci_disable_intr() and
rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet
offload can't receive c2h back due to interrupt disable. Only 8852C and
8922A needs to disable interrupt before downloading fw.
Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent
interrupt enabled, then get interrupt and calculate RXBD mismatched due to
software RXBD index already reset but hardware RXBD index not yet.

Remove unnecessary includes from driver. The first step is to add
necessary includes to driver's header files to make them can be included
individually. Then, driver's C files include driver's header files first,
and check if still missed header files of kernel.
The results show that most C files only include driver's header files.
Only core.c needs to include additional linux/firmware.h.
Also sort includes in alphabetic order.
Compile tested only.

The driver is already in a directory named rtl8xxxu, there's no need to
duplicate that in the filename as well. Now file listing looks a lot more
reasonable:
8188e.c 8192c.c 8192f.c 8723a.c core.c Makefile rtl8xxxu.h
8188f.c 8192e.c 8710b.c 8723b.c Kconfig regs.h

I noticed by random that rtl8xxxu includes linux/wireless.h even though it

include files:
#include <linux/init.h>
#include <linux/sched.h>
#include <linux/ethtool.h>
It looks like that the includes are just copied to every file without checking
if the file really needs the include. So more includes could be removed but
that would need more careful analysis per each file.

Create the new module rtl8192d-common and move some code into it from
rtl8192de. Now the rtl8192de driver (PCI) and the new rtl8192du driver
(USB) can share some of the code.
This is mostly the code that required little effort to make it
shareable. There are a few more functions which they could share, with
more changes.
Add phy_iq_calibrate member to struct rtl_hal_ops to allow moving the
TX power tracking code from dm.c.
The other changes in this patch are adjusting whitespace, renaming some
functions, making some arrays const, and making checkpatch.pl less
unhappy.
rtl8192de is compile-tested only. rtl8192d-common is tested with the
new rtl8192du driver.

Different channels have different TX power settings. rtl8192de is using
the TX power setting from the wrong channel in the 5 GHz band because
_rtl92c_phy_get_rightchnlplace expects an array which includes all the

variables order, so driver does changes accordingly.

When the PTA breaks Wi-Fi traffic request caused Bluetooth traffic,
it means Bluetooth polluted the Wi-Fi traffic. When Wi-Fi is TX, the
mechanism can ignore the polluted Wi-Fi packet retry counter, it is
help to the stability of Wi-Fi TX rate. The chip RTL8922A has not only
one MAC, so need to include the all MAC as reference.

PTA(packet traffic arbitration) is a coexistence hardware feature.
Wi-Fi & Bluetooth owns their PTA, the function is to show whose PTA
control the traffic now. RTL8922A PTA control is controlled by hardware
logic, there is no register to monitor the setting.
